SUPPORT FOR IVIOTIVE-POWER AGENCIES.

SPECIFICATION forming part of Letters Patent No. 732,872, dated July '7, 1903.

Application filed August 9, 1901. sent] No. 71,519. (No model.)-

To all whom it may concern.-

Be it known that I, HERMANN LEMP, a citizen of the United States, residing at Lynn, in the county of Essex, State of Massachusetts,

have invented certain new and useful Improvements in Supports for Motive-Power Agencies, of which the following is a specification.

Myinvention relates to the means employed for supporting motive-power agencies on antomobiles, and more particularly to those employing steam-engines to furnish power.

The invention has for its object to improve the construction of the supporting means, and

the scope of my invention will be more fully set forth and claimed hereinafter.

In the accompanying drawings, which illustrate my invention, Figure 1 is a vertical section of a steam-propelled vehicle. Fig. 2 is a plan view thereof with the body removed. Fig. 3 is a detail of one typeof hanger, and Fig. 4 is a detail of a difierent type of hanger.

1 and 2 represent the fixed axles of thevehicles, and pivoted to the front axle are two short axles 3, forming a part of the wellknown double-axle steering mechanism. The rear wheels are mounted directly on the axle 2 and are mechanically connected to the engine by sprocket-chains 4, one chain being provided for each wheel. The short front axles are connected by a suitable system of levers, which in turn are connected to the steering-handle 5.

The carriage-frame is constructed of tubes, is substantially rectangular in form,'and is supported at the rear end by short extensions 6 of the side tubes, which tubes are secured to brackets 7. The front end of the frame is supported by tubes 8, which are. secured in brackets 9. i The tubes 8 are brought somewhat nearer together than the side tubes of themain frame in order that the front wheels may have a greater range of movement about the vertical pivots. Both'the frame and the driving mechanism are supported by four full ellipticsprings 10, the latter being secured to the axles by suitable brackets.

' The engine 11 is of the four-cylinder singleacting type, and, as shown, the casing is di vided into two parts, two cylinders being in each part, with a piece 12 for uniting them.

will be sufficient. Bolted or otherwise secured to the top of the engine is a plate or projection 14, to which the horizontally-extending rods 15 are secured. These rods pass through the transverse frame bars or tubes 13 and are secured by nuts 16, as illustrated in detail Fig. 4. The opposite ends of the rods are provided with heads, which engage with the plate 14. By adjusting the position of the nuts on the different rods the position of the engine can be shifted slightly forward or back. The lower portion of each truss is composed of two rods 17, which are secured to the lower portion of the engine-frame by bolts 18.. Oneofthe bolts passes verticallythrough a flange on the engine-frame, while the other bolt extends longitudinally into the frame. The rods 17 are secured to'the transverse frame-tubes by hangers. The end of each rod is screw-threaded to receive a flat plate 1 9, and this plate is secured to the U-shaped clamp 20, forming a part of the hanger, by nuts 21, Fig. 3. This construction is a desirable one, as the hangers can be shifted transversely, thus obviating the necessity of 8 5 careful machine-work.

The engine or motive-power agency is provided with a main shaft 22, that is connected to the several pistons in the ordinary manner. Located on the main shaft between the 0 inner cylinders isapinion 23. (Shown in dotted lines.) This pinion meshes with a gear 24, carried by the intermediate shaft 25. Thegearing is inclosed by a two-part gear-case 26. The gear-case may be so arranged that one 5 portion of it is formed integral with or is secured to the engine-frame. The intermediate shaft is divided in a plane passing vertically through the center of the gear-case, and on the end of each part of the shaft is mount- :00 ed a gear, which gear meshes with piniongears 27, carried by the gear 24, the whole constituting the well-known differential system of gearing, by means of which one part of the intermediate shaft is permitted to revolve at a different speed than the other partas, for example, when the vehicle is moving in the arc of a circle. The opposite sides of the gear-case are provided with bearings, which are sleeved on the two parts of the intermediate shaft.

Formed on the engine-casing or otherwise secured thereto are bearings 28 for the adjacent ends of the intermediate shaft. The ends of the intermediate shaft are extended outward between the members of the trusssupport for the engine and are provided with bearings 29, carried by the hangers 30. The

hangers are supported by the side frametubes and can be adjusted to the proper position, after which they are secured in place. On the ends of the intermediate shaft are sprockets 31, which carry the sprocketchains 4.

The engine-support as illustrated and described constitutes what might be called a queen-post? truss, wherein the rods 15 and plate 14 constitute the tie-beam, the downwardly-extending rods 17 the truss-beam, and the engine 11 the queen-post, which is common to both trusses. By means of the structure described the motive-power agency can be readily adjustedand alined and when so adjusted and alined is securely held in position.

i What I claim as new, and desire to secure by Letters Patent of the United States, is

1. In an automobile the combination of a frame, a motive device, a main shaft, a twopart intermediate shaft, bearings secured to the side tubes of the frame for supporting the outer ends of the intermediate shaft, differential gearing between the inner ends of the intermediate shaft, gearing between the main and intermediate shaft, 3. gear-casing for inclosing the gears, and bearings carried by'the engine for supporting the intermediate shaft at the point of division.

2. In combination, a vehicle-frame, an engine, and a pair of queen-post trusses for supporting the engine, the said trusses being located at opposite ends of the engine-frame.

3. In a vehicle, the combination of a frame composed of side and end members, an engine, truss-supports for the engine which are secured to the engine and to the side members of the frame, a shaft for transmitting motion to the driving-wheels, and bearings for the shaft which are mounted on the side members of the frame.

4. In a vehicle, the combination of a frame composed of side and end members, an engine, supports for the engine, a driving-shaft, bearings carried by the engine for supporting the intermediate portion of the shaft, and beariugs carried by the frame for supporting the outer ends of the shaft.

5. In combination, a vehicle-frame, a motor, rods which connect the parts of the frame together and form a tie-beam to which the upper part of the motor is secured, and other rods which are secured to the frame and form a truss-beam to which the lower end of the motor is secured; the said rods forming the sole support for the motor.

6. In combination, a vehicle-frame having transversely-extending members, a motor located between said members, rods which connect said members and are secured to the upper end of the motor, and other rods which also connect the members and are secured to the lower end of the motor; the said rods and frame members forming a truss.

7. In a vehicle, the combination of a frame, and engine having a two-part casing which parts are rigidly connected, a gear located between the parts, a casing inclosing the gears which is supported by the engine, means for supporting the engine, an intermediate shaft, a bearing on the engine for the shaft, and bearings on the frame for supporting the outer end of the shaft. I

8. In a vehicle, the combination of a frame, an engine, a projection thereon, truss-rods which are secured to the projection and to the frame, and other rods which are secured to the engine-casing and to the frame.

9. In a vehicle, the combination of a frame, a motor which is adjustable thereon, and a pair of adjustable queen-post trusses which support the motor below the frame.

10. In a vehicle, the combination of a frame, an engine, a pair of trusses located at opposite ends of the engine, the latter forminga queenpost which is common to both trusses.

In witness whereof I have hereunto set my hand this 7th day of August, 1901.
